Description

  The present invention relates to a handrail that is installed in a toilet, a bathroom, and the like, and in particular allows an elderly person or a disabled person to use the toilet safely.

  As this type of handrail, there is known a handrail provided with an L-shaped handrail body composed of a horizontal bar portion and a vertical bar portion extending upward or downward from one end of the horizontal bar portion. The handrail main body is integrally formed of a metal pipe or a resin pipe, and is attached to the wall surface by a plurality of brackets.

  In the case of the above L-shaped handrail, since one end of the bracket is normally fixedly connected to the handrail main body, it is impossible to install it across, for example, two intersecting wall surfaces constituting a corner. The location was limited to a single flat wall.

Further, as an L-shaped handrail, there has been conventionally known one in which an attachment portion to a wall surface provided at a rear end portion of a bracket is made variable by a ball joint (see Patent Document 1 below).
In the case of this handrail, the ball joint provided at the bracket mounting part can absorb the vertical error of the wall surface, thereby improving the workability, but the variable angle is not so large, so it also constitutes the corner. It was impossible to install across two intersecting walls.

In addition, in the case of this type of handrail, it is necessary to determine the size of the handrail body according to the size of the installation location and the needs of the user. In the case of the conventional L-shaped handrail described above, the handrail body is integrally formed. Therefore, there is a problem that it is difficult to change the size, and even if it corresponds, it takes time and the cost is high.

  An object of the present invention is to provide a handrail that can solve the above-described problems and can widely meet the needs of installation locations and users.

  A first handrail according to the present invention includes a handrail main body in which a vertical bar is connected in series to at least one vertical end of a horizontal bar whose both ends are bent vertically upward or downward, and the handrail main body is horizontally disposed. It is provided with three or four brackets for fixing to the wall surface at both vertical ends of the bar and at the tip of each vertical bar. At one end of each bracket is formed a holding cylinder that is rotatably fitted to the vertical end of the horizontal bar or the tip of the vertical bar, and the vertical end or vertical bar of the horizontal bar constituting the end of the handrail body The front end portions of the first and second end portions cannot be detached from the holding cylinder portion by stoppers attached to the front ends. And the attachment part attached to a wall surface by the fixing means is formed in the other end part of each bracket.

  In the first handrail, by rotating each bracket around the vertical end of the horizontal bar or the front end of the vertical bar, the orientation of the bracket mounting portion can be freely changed within a range of 360 °. Can do. Therefore, according to the above-mentioned handrail, it is not only installed on a single flat wall surface, but also installed across two intersecting wall surfaces constituting a corner, or on two substantially parallel wall surfaces shifted in the horizontal direction. It can also be installed across.

  In the case of the first handrail, since the handrail main body is configured by connecting a horizontal bar and a vertical bar formed separately from each other, the lengths of the horizontal bar and the vertical bar to be used are appropriately set. By changing it, it is possible to quickly respond to the size of the installation location and the needs of the user, and the cost does not increase.

  Next, a second handrail according to the present invention is provided for fixing a handrail main body composed of a horizontal bar whose both ends are bent vertically upward or downward, and a handrail main body to a wall surface at both vertical ends of the horizontal bar. It is provided with two brackets. One end of each bracket is formed with a holding cylinder that is rotatably fitted to the vertical end of the horizontal bar, and the vertical end of the horizontal bar cannot be removed from the holding cylinder by a stopper attached to the tip of the horizontal bar. It has been. And the attachment part attached to a wall surface by the fixing means is formed in the other end part of each bracket.

  In the second handrail, the direction of the mounting portion of the bracket can be freely changed within a range of 360 ° by rotating the bracket around the vertical end portion of the horizontal bar. Therefore, according to the above-mentioned handrail, it is not only installed on a single flat wall surface, but also installed across two intersecting wall surfaces constituting a corner, or on two substantially parallel wall surfaces shifted in the horizontal direction. It can also be installed across.

  In the first or second handrail according to the present invention, it is preferable that a horizontal intermediate portion between both vertical end portions of the horizontal bar is curved in one direction as viewed from the plane.

As described above, if the horizontal intermediate portion of the horizontal bar is curved in one direction when seen from the plane, the horizontal intermediate portion is convex toward the front and the rear is convex toward the rear. It is possible to appropriately select two installation modes without permission.
Specifically, for example, a toilet with a small space and a Japanese toilet bowl installed at an angle will be replaced with a Western-style toilet so that it can be easily used by the elderly and the disabled. There may be a renovation to install. In this case, if the first or second handrail is installed so as to straddle the two wall surfaces constituting the corner and the horizontal intermediate portion of the horizontal bar is in front, the horizontal intermediate portion of the toilet bowl and the horizontal bar And the distance will be closer. On the other hand, if the first handrail or the second handrail is installed so as to straddle the two wall surfaces and the horizontal intermediate portion of the horizontal bar is in the back, the distance between the toilet and the horizontal intermediate portion of the horizontal bar is It will be far away. Therefore, according to the said structure, according to the size of an installation place and a user's needs, it is possible to adjust the distance of a toilet bowl and the horizontal intermediate part of a horizontal bar easily, and is convenient.
